I have the stove paint for an exhaust used. The color easy to work with and dries very quickly. After the first painting I have grown to exhaust again and after 1 him - hot drove 2 hours so that the paint will burn. Subsequently, the exhaust was dismantled, and slightly roughened with 400 grit sandpaper. After the 2nd and 3rd varnish was made. All top. Long-term experience, I have not, of course.
